nobody talks about how agents get worse at following instructions when you give them more context
been building tooling around this for like two years now and I keep hitting the same wall. you'd think giving an agent more information would make it better at its job. but there's this weird inflection point where it just starts... ignoring what you asked for.
I had a case last month where I fed an agent a document with relevant info plus some tangential stuff. simple task, explicit instructions. it did fine. then I added more context thinking it'd help with edge cases. suddenly it's off doing something completely different, citing details from the extra context instead of following the original directive.
it's like the agent gets confused about what actually matters. or maybe it's treating everything as equally important and just picks random threads to follow. I'm still not sure which.
has anyone else run into this? like how do you actually figure out if it's a training thing or a fundamental issue with how these systems weight information?
